Generalized discharge equations for HS and H flumes were developed from the original data. Discharge equations for the HL flume were developed from a published rating table for a 4-ft (1.2-m) flume. The equations are expressed in the basic dimensions of the control section. A direct solution for the effect of submergence on H flumes is presented in equation form.
